There are few conversions in HVAC as simple as MBH to BTU/h. Basically, we are converting a thousands British Thermal Units per hour (MBH) to British Thermal Units per hour (BTU/h or BTU/hr). To help you out with the conversion, we prepared an MBH to BTU/h calculator (insert MBH, get BTU/h) as well as a 0.01-50 MBH to BTU/h conversion chart.
Quick Example: Say you want to convert 12 MBH to BTU/h. You just insert 12 MBH in the calculator (or check the chart below), hit ‘Calculate’, and the calculator tells you immediately that 12 MBH is equal to 12,000 BTU/h.
Here is this online calculator:
You can try inputting, say, 36 MBH in the calculator and see that you will get the BTU/h equivalent as a result (36 MBH is equal to 36,000 BTU/hr). You can do this conversion in reverse with this BTU/h to MBH calculator.
Let’s have a look at how simple this conversion is (we can do the math in our head):
MBH To BTU/h Formula
MBH in HVAC stands for ‘thousand BTUs per hour’. That ‘M’ is just a Roman numeral M that means ‘thousand’ or ‘1000’. When we calculate heating or cooling capacities, we just use this conversion rule (it’s in the name):
1 MBH = 1000 BTU/h
Namely, 1 MBH is equal to 1000 BTU/h. We can write this relationship in the following equation:
BTU/h = MBH ร 1000
To convert MBH to BTU/h, we just need to divide MBH by a factor of 1000 to get the BTUs/h.
Quick Example: How many BTU/h is 9 MBH? Let’s insert 9 MBH in the formula above and calculate the result:
BTU/h (9 MBH) = 9 MBH ร 1000 = 9000 BTU/h
We see that 9 MBH is equal to 9000 BTU/h. Many portable and window air conditioners, for example, have 9 MBH or 9000 BTU/h cooling capacity.
You can do this calculation in your head but just for a bit of added help, we created this neat MBH to BTU/hr chart you can check and get the BTU/h right away:
